Product Specification

MS-802 Secondary Standard Pyranometer Description
The MS-802 Secondary Standard Pyranometer is the ultimate reference sensor to measure global solar irradiance with the highest precision. Its robust brass mechanical construction makes it a durable sensor suitable to be used in harsh environments. The MS-802 is used as standard for PV research and climatol- ogy studies around the world.

In combination with a Sun tracker (STR-series) or manual shading ring (RSR-01), respectively the Global Normal Incidence (GNI) and Diffuse (DHI) irradiance can be measured. The MS-802F is a MS-802 with integrated ventilator unit to improve the performance under various environmental conditions (prevents or minimizes the effect of dew, rain, snow, ice and dust).

MS-802 Secondary Standard Pyranometer Features
? Secondary Standard Pyranometer
? Fast Response Time (95% < 5S)
? Temperature Compensated In A Wide Temperature Range
? High Quality Optical Glass Domes For Proper Cosine Response
? MS-802F is an MS-802 with a 110 VAC/12 VDC Ventilation System To Prevent Any Possible Influince Of Frost, Snow And Dus
